I recently installed an AMD Athlon XP 2500+ CPU on my ASUS A7V333 motherboard as an upgrade. When I booted up the PC, it kept having memory errors and just wouldn't work. The BIOS is fully up to date for the CPU's support yet nothing gives. I even reinstalled the previous CPU I had for the A7V333 and it STILL reports memory errors. Any help as to what the problem could be?
